Answer:
The price per pound of apples is greater than $1.
Step-by-step explanation:
Please consider the complete question:
Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?
To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.
[tex]\text{Price of apples per pound}=\frac{\$2.88}{2.1}[/tex]
[tex]\text{Price of apples per pound}=\$1.37142857[/tex]
Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.
To find the price per pound of apples, we divide the total cost of the apples by the weight of the apples.
Explanation:To determine whether the price per pound of apples is greater or less than $1, we need to divide the total cost of the apples by the weight of the apples. The question states that Laura bought 2.1 pounds of apples. To find the total cost, we can use the information given in the reference:
10 apples × 50 cents each = $5.00 spent on apples in 2001.
Dividing $5.00 by 2.1 pounds gives us the price per pound of apples Laura bought, which is approximately $2.38. Therefore, the price per pound of apples is greater than $1.

Answer:
GCF = 5
Step-by-step explanation:
Given:
The numbers are given as:
10, 30 and 45
A factor of a number is a number by which the given number is evenly divisible.
Example: 2 is a factor of 4 as [tex]4\div 2 =2[/tex]. So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.
Now, factors of 10 = 1, 2, 5, 10.
Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 45 = 1, 3, 5, 9, 15, 45.
So, the greatest common factor in all the three numbers is 5.
Hence, the greatest common factor of 10, 30 and 45 is 5.

Choose the solution set graphic until the correct one is displayed.
A.Infinite set of points on the line
B.Empty set
C.Points on negative x-axis
Final answer:
The solution set graphic is C - Points on negative x-axis.
Explanation:
The correct solution set graphic for this question is C - Points on negative x-axis.
To determine the solution set graphically, you would need to plot all the possible values of the equation or inequality on a coordinate plane. Option A - Infinite set of points on the line would represent a linear equation or inequality with multiple solutions. Option B - Empty set would mean that there are no solutions to the equation or inequality. Option C - Points on negative x-axis would indicate that the equation or inequality has solutions only on the negative x-axis.
Which of the following rational numbers represents a repeating decimal 11 / 40 ,3/25, 25/48,or 7/32
[tex]\frac{25}{48}[/tex] represents repeating decimal
Solution:
We are asked to find the rational number that represents repeating decimal
A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely)
Option 1
[tex]\frac{11}{40} = 0.275[/tex]
So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal
Option 2
[tex]\frac{3}{25} =0.12[/tex]
So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal
Option 3
[tex]\frac{25}{48} = 0.52083333333[/tex]
So here in decimal part "3" is repeating and goes on forever
So [tex]\frac{25}{48}[/tex] represents repeating decimal
Option 4
[tex]\frac{7}{32} = 0.21875[/tex]
So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal
a bag contains 5 red, 6 white, and 5 blur marbles. a marble is drawn from the bag and replaced 32 times. the table shows the results. for which color is the experimental probability of drawing the color the same as the theoretical probability?
red:12 white: 12 blue:8
Answer:
White.
Step-by-step explanation:
Theoretical probabilities are:
Red: 5 / ( 5 + 6 + 5) = 5/16
White: 6/16 = 3/8.
Blue: 5/16.
The answer is white because it is drawn 12 times which equals its theoretical probability: 12/32 = 3/8.
The probability of drawing the color the same as the theoretical probability is 3/8.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A bag contains 5 red, 6 white, and 5 blue marbles.
Theoretical probabilities for the colors are:
Red:
= 5 / ( 5 + 6 + 5)
= 5/16
White:
= 6/16
= 3/8.
Blue: 5/16.
So, the probability of drawing the color the same as the theoretical probability is white because the theoretical probability is 3/8.

Good morning,
Answer:
-19
Step-by-step explanation:
(5x−3)/2=3x+8 ⇌ 5x−3 = 2×(3x+8) ⇌ 5x−3 = 6x+16 ⇌ 6x-5x = -3-16
⇌ x=-19.
:)
Answer:
x = - 19
Step-by-step explanation:
Given
[tex]\frac{5x-3}{2}[/tex] = 3x + 8
Multiply both sides by 2 to clear the fraction
5x - 3 = 6x + 16 ( subtract 6x from both sides )
- x - 3 = 16 ( add 3 to both sides )
- x = 19 ( multiply both sides by - 1 )
x = - 19
Find the other endpoint given one endpoint (-1,6) and the midpoint is (4,2)
Answer:
The required points of the given line segment are ( 9, - 2 ).
Step-by-step explanation:
Given that the line segment AB whose midpoint M is ( 4, 2 ) and point A is ( - 1, 6), then we have to find point B of the line segment AB -
As we know that-
If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-
M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1} + y_{2}}{2}[/tex] )
Here,
Let A ( - 1, 6 ), B ( x, y ) with midpoint M ( 4, 2 ) -
then by the midpoint formula M are-
( 4, 2 ) = ( [tex]\frac{ - 1 + x}{ 2}[/tex] , [tex]\frac{ 6 + y}{2}[/tex] )
On comparing x coordinate and y coordinate -
We get,
( [tex]\frac{ -1 + x}{2}[/tex] = 4 , [tex]\frac{ 6 + y}{2}[/tex] = 2)
( - 1 + x = 8, 6 + y = 4)
( x = 8 + 1, y = 4 - 6 )
( x = 9, y = -2 )
Hence the required points A are ( 9, - 2 ).
We can also verify by putting these points into Midpoint formula.

Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been using for collecting his coins and finds he has 47 coins that are worth $9.50. How many of each coin does he have?
Answer:
He have 32 quarters and 15 dimes.
Step-by-step explanation:
Given:
Asa saves dimes and quarters so that he will have exact change for the bus.
He has 47 coins that are worth $9.50.
Now, to find the number of coin each he have.
Let the number of quarters be [tex]x.[/tex]
And the number of dimes be [tex]y.[/tex]
So, the total number of coins are:
[tex]x+y=47.[/tex]
[tex]y=47-x.[/tex].........(1)
As given the total worth of coins = $9.50
And the value of a quarter = $0.25 and the value of a dime = $0.10.
Now, the total worth of coins are:
[tex]0.25x+0.10y=9.50[/tex]
Putting the equation (1) in the place of [tex]y[/tex] we get:
[tex]0.25x+0.10(47-x)=9.50[/tex]
[tex]0.25x+4.7-0.10x=9.50[/tex]
[tex]0.15x+4.7=9.50[/tex]
Subtracting both sides by 4.7 we get:
[tex]0.15x=4.80[/tex]
Dividing both sides by 0.15 we get:
[tex]x=32.[/tex]
The number of quarters = 32.
Now, putting the value of [tex]x[/tex] in equation (1) we get:
[tex]y=47-32.[/tex]
[tex]y=15.[/tex]
The number of dimes = 15.
Therefore, he have 32 quarters and 15 dimes.
